Honestly there is an obvious intended sadness that permeates this film and it's characters. While on the one hand it's not the gritty end, like the Dirty Dozen or the Wild Bunch, these rogues weren't bad or angry enough, going out.
On the other extreme it's obviously not (and it wasn't meant to be) the Joyful end for them, like Return of the Jedi. It's just somewhere in between, ... sad.
That said I did Love the movie, despite what little time to develop all the characters got:
These aren't the ones who get the medals, the kiss from the princess, the recognition, the glory, or any reward. To the contrary.
Instead we get a ragtag, gloomy, spent, band of Rebel outsiders, yet with plenty of strength, heart and conviction to die doing what everyone else writes off as a doomed, hopeless mission.
There is no one else for it, and they kind of know it has to be them.
-Jyn Erso; character who'd lost her way, stopped caring ""It's Not A Problem If You Don't Look Up." until she finds the truth about her father, who gives her something to fight for again, and a bit of a lost and familiar family in these Rogues, to bring back hope to a once lost cause.
-Cassian Andor: A unique look at a darker side of a Rebel fighter, who'd been doing it so long, following orders, killing, he'd lost his own humanity (and tragically knew it), to the point where there was no turning back, all that was left for him (and his team),to feel like human beings again, was this suicide mission to at least bring about that last hope to others.
-K2-SO: Ironically the cold gunmetal Imperial Assassin droid, Cassian who had lost his own humanity (and become the cold assassin), reprograms to be more human than himself, like if he couldn't be that, his Droid would.
-Bodhi Rook: The Imperial working stiff, cargo pilot, with mundane job, family, routine, who one day risks it all, just makes a decision to do something, and ultimately changes the fate of the Galaxy. (This guys probably the hardest sell as a figure, particularly because the whole point of the character is he's not supposed to stand out, or look like any hero, he could be delivering packages. Yet he chooses to go out a hero.
-Chirrut Imwe: the blind spiritual Warrior (who "sees" in the darkness what everyone else misses) "The Cage we carry within) clinging to a lost mysticism and way, that guides him (or so he wants to believe), and ...
-Baze Malbus: His silent with a big-gun that speaks for him, loyal (to the end) companion, who'd lost his belief, but finds strength in his friends dying action. Bit of a cliche/classic trope, but in the tradition of what Lucas drew from, pulled in to this film fits great into the SW U, and this team's inevitable end.
Great little ensemble team, with small character arcs,, buried within a bigger war/heist epic, with a simple mission; We don't matter, and never will, all that matters is get the plans (and hope) into the right hands, the hands that do matter) that's them, their knowing sacrifice.
That's also exactly why they aren't getting allot recognition (or figures), and will mostly be forgotten. It's exactly who they were set up to be! Forgotten. LOL! So I'm not surprised at the lack of figures or attention.
In the end they are culled from one moment and line in the classic opening crawl,
"...During the battle, Rebel spies managed to steal secret plans to the Empire's ultimate weapon,..."
blink, and in the big picture you missed it, and them.
Maybe if Cassian had been released at the same time as Jyn , or they'd come together I would have got both. But alone Jyn seemed not to fit anywhere, and then again K2 without Cassian still seems adrift.
